Privacy SMS and Account Compartmentalization: A Practical Guide

How to separate personal phone identity from low-risk web testing and sign-up experiments.

Compartment model

• Personal number: family, banking, healthcare, durable accounts
• Work number: business communication and internal systems
• Disposable testing path: low-risk sign-up experiments and QA

Evidence hygiene

• Record what was tested and why
• Delete screenshots that contain unnecessary personal data
• Avoid forwarding codes into shared team channels

Tooling

• A privacy SMS verification option belongs in the disposable testing compartment, not in the durable identity compartment.
